On the one hand, the difficulty of newly-built substations or net racks is increased, and on the other hand, the backbone net racks of the power grid which are built at present are not fully utilized. According to the load demands of different areas, the sections of the lines are different when the lines are built, the current-carrying capacity of the lines is different, the load rate of the lines of the partial area is close to the current-carrying capacity along with the continuous aggravation of the contradiction between the supply and demand of electric power, the power can be supplied at the moment of peak load in a rotating way to ensure that the lines are not overloaded, the load rate of the lines of the partial area is lighter, and the power transmission capacity of the grid is not exerted.
